Answer:
A
Step-by-step explanation:
Note
One thing you should automatically notice is that x is larger, much larger than 20. x is the hypotenuse of a right triangle
Formula
Sin(18) = opposite side / hypotenuse
Givens
Sin(18) = 0.30902
opposite = 20
hypotenuse = x
Solution
sin(18) = 20 / x Multiply both sides by x
x sin(18) = 20*x /x
x sin(18) = 20 Divide by sin(18)
x sin(18) / sin18 = 20/sin(18)
x = 20 / 0.30902
answer: x = 64.72
Answer:
Hey mate......
Step-by-step explanation:
This is ur answer.....
<h3>Complement Angle = 90° </h3>
<em>= 90 - 18</em>
<em>= 72</em>
<em>--</em><em>></em><em> </em><em>7</em><em>2</em><em>°</em><em> </em><em>is</em><em> </em><em>the</em><em> </em><em>complement</em><em> </em><em>angle</em><em> </em><em>of</em><em> </em><em>1</em><em>8</em><em>°</em>

Step-by-step explanation:
a) The slope formula is given by
m = (y2 - y1)/(x2 - x1)
Let P1(7, 5) and P2(21, 15)
m = (15 - 5)/(21 -7)
= 10/14
= 5/7
b) Let's see if the slope is only a third of the one found in part (a) or m = 5/21. Let P1(0, 0) and P2(21, 5).
m = (5 -0)/(21 - 0)
= 5/21
Indeed, the slope is only a third of part (a), as we predicted.
